Examples of Tax Increases from Surtax July 20, 2009 Gerald Prante Gerald Prante The following is a table showing just the surtax amount that tax returns at various adjusted gross income (AGI) levels would be hit with in 2011 under the proposed health care bill in the House. Note that in 2013, the surtax on those with AGI less $1 million ($800,000 for singles) may increase, depending upon the savings from the health care bill. There appears to be some confusion regarding the marginal tax rate concept, which is the tax imposed on the next dollar of income earned. A marginal tax rate is not the same as an average tax rate. Furthermore, the surtax would not apply to all income. It would only apply to income earned beyond $350,000. If some married couple earns $400,000, they would not pay the 1 percent surtax on the entire $400,000. The couple would only pay surtax on 1 percent of the difference between $400,000 and $350,000, which equals $50,000 x .01, or $500.
